Warranties are a lie!!!!

I need to speak to someone with regards to my Iwatch being repaired Urgently. I was informed that as there is no physical damage on my watch that caused the screen to crack. That it would be covered under my warranty. I have had this watch for only 3-4 months and is the second watch i have had in the past year that the screen has cracked. i was informed that i need to pay for the screen to be fixed which is totally unacceptable. I payed for the first watched to be replaced and now the same issue happened again on my second watch. There is clearly a unit deficiency that is causing the screen to crack the exact same way my first watch did. Please can you get someone to contact me urgently so we can resolve this as this is very bad customer service!!!!!!!!!!!!
